ERJ-S14F1870U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1870U is a 187 Ohm ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with 836 pieces available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F1870U are qualified based on the following electrical and mechanical parameters:

• Resistance value: 187 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

All substitute parts listed maintain these critical parameters, ensuring direct functional and mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S14F1870U (Primary Selection) This part is recommended for new designs and ongoing production. It maintains active product status with anti-sulfur coating, full AEC-Q200 automotive qualification, and ROHS3 compliance. Tape & Reel packaging supports high-volume automated assembly operations.

ERJ-14NF1870U (Legacy Alternative) This Panasonic part is electrically and mechanically identical to the main part but carries "Not For New Designs" status. It remains suitable for replacement, repair, and sustaining production of existing designs where supply of the primary part is unavailable. Tape & Reel packaging is maintained.

RMCF1210FT187R (Cross-Manufacturer Alternative) This Stackpole Electronics part provides equivalent electrical and mechanical performance with active product status. It differs only in packaging format (Cut Tape instead of Tape & Reel), which may require process adjustment for automated assembly. Selection is appropriate when Panasonic parts experience supply constraints and packaging flexibility exists in the manufacturing process.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1870U be used as a direct replacement for ERJ-S14F1870U? A: Yes. Both parts share identical electrical specifications (187 Ohms ±1%, 0.5W), package dimensions (1210), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status; ERJ-14NF1870U is not recommended for new designs but remains suitable for replacement applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape supplies components on tape segments, typically used for lower-volume or manual assembly processes. Both formats contain identical components; packaging selection depends on assembly equipment and production volume requirements.

Q: Are all substitute parts AEC-Q200 qualified? A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, meeting the same reliability and quality standards as the primary part.

Q: Do substitute parts maintain the same temperature performance? A: Yes. All substitute parts operate across the identical temperature range (-55°C ~ 155°C) with the same temperature coefficient (±100ppm/°C), ensuring equivalent thermal performance in circuit applications.

Q: Is RoHS compliance maintained across all substitute parts? A: Yes. All substitute parts are ROHS3 compliant, matching the environmental compliance status of the primary part.
